All-on-4 upper jaw rehabilitation with MegaGen AnyRidge implants

All-on-4 upper jaw rehabilitation with MegaGen AnyRidge implants
Complaints:
Missing teeth, inability to chew food properly, and pain in the temporomandibular joint.
Diagnosis:
Secondary edentulism of the upper jaw.
Treatment:
During the diagnostic stage, a computed tomography (CT) scan was performed. Based on the findings, the patient was offered full-arch implant rehabilitation using the All-on-4 concept. A 3D treatment plan was created. Intraoral digital scanning of the jaws was performed using a 3Shape scanner, and a surgical navigation guide was fabricated. In addition, a gnathological analysis was carried out to correct occlusal relationships, stabilize the mandibular position, and reduce excessive loading on the temporomandibular joint. Korean MegaGen AnyRidge implants were placed according to the All-on-4 protocol. Immediate loading of the four implants was performed using a temporary prosthesis reinforced with a titanium bar during the osseointegration period, allowing the patient to immediately regain esthetics and masticatory function. After 6 months, implant osseointegration and soft tissue stability were evaluated. Following successful implant integration, a permanent zirconia prosthesis reinforced with a custom titanium bar was fixed using screw-retained fixation and supported by four implants.

In this case, the absence of teeth in the upper jaw was accompanied not only by an inability to chew food properly, but also by pain in the temporomandibular joint area.

Therefore, the treatment was aimed not only at restoring the teeth, but also at normalizing occlusal relationships.

After CT imaging, 3Shape digital scanning, 3D treatment planning, and gnathological analysis, rehabilitation was performed according to the All-on-4 concept using MegaGen AnyRidge implants.

An individual surgical guide was fabricated to ensure precise implant placement.

On the day of surgery, the patient received a temporary fixed prosthesis on a titanium bar, which immediately restored both smile aesthetics and chewing function.

After 6 months of successful osseointegration, the temporary restoration was replaced with a permanent zirconia prosthesis on a custom titanium bar with screw retention.

Result:

The upper jaw teeth, chewing function, and smile aesthetics were fully restored.

It was also possible to stabilize the bite and reduce the load on the temporomandibular joint.

 

TMJ pain and missing teeth are often interconnected and require a comprehensive treatment approach.
